@printedwaffles the RAM cannot be upgraded. The Yoga 2 13 has 2 slots: 1 m.2 (that is now used for your SSD) and another connector for a 2.5" storage device. For some models this is a normal SATA connector, but for most it is a very rare SFF-8784 connector that only connects to the 5mm WD HDD. Found these for part numbers ZIVY0 HDD Bracket : 90205123[br]
